3 Top-Ranked Municipal Bond Funds to Buy for Stable Income

The article highlights three municipal bond mutual funds with Zacks Rank #1 “Strong Buy”—Colorado BondShares Tax-Exempt (HICOX) with 3-year annualized returns of 6.3%, Eaton Vance Total Return Bond (EIBAX) at 5.8%, and American High-Income Municipal Bond (AMHIX) at 5.1% (AMHIX expense ratio: 0.68%). It emphasizes tax advantages (federal, and often state) and the income/capital preservation rationale versus plunging stocks. Overall, the tone is constructive for risk-averse income investors, but the impact is mainly promotional/analyst-driven rather than a major market-moving event.

Analysis

This reads less like a fund recommendation and more like a positioning signal: when investors are pushed toward tax-exempt, income-first vehicles, the marginal buyer is usually de-risking. That is a modest headwind for NNOX because names that live on future growth optionality, not current cash generation, tend to lose sponsorship first when portfolios rotate toward yield and balance-sheet certainty.

The relevant mechanism is liquidity, not fundamentals. If real yields stay elevated and credit investors remain defensive, long-duration equity multiples compress before operating results change, and that is where speculative med-tech gets hit hardest. The offset is that any meaningful drop in Treasury yields or tightening in spreads can quickly re-open the financing window and trigger a sharp rebound in the most beaten-down growth pockets.

The contrarian point is that not all muni-fund interest is bearish macro; some of it is just after-tax yield harvesting, especially from accounts with state-tax sensitivity. So the article is a weak standalone signal. For NNOX specifically, the market should ignore promotional language unless it is backed by sequential revenue acceleration or a visibly lower dilution risk; otherwise any bounce is likely liquidity-driven and prone to fade.

Key Decisions for Investors

• Short NNOX vs long IHI or XLV for 1-3 months as a liquidity-sensitive pair trade; thesis works if higher-for-longer rates keep compressing speculative med-tech multiples. Cover if NNOX shows two straight quarters of meaningful revenue acceleration or announces non-dilutive financing.
• Do not chase the muni-fund theme directly; HICOX/EIBAX/AMHIX are not efficient desk expressions. If you want the defensive read-through, use MUB or VTEB as the liquid proxy.
• If rates back up again, add to a small NNOX short on strength rather than weakness; the best entry is into any promotional pop that is not supported by hard operating data. Risk is a sharp short squeeze if Treasury yields break down and growth re-rates.
• Set an alert on the 10-year Treasury and credit spreads: a sustained move lower in yields with stable spreads is the main falsifier for the bearish NNOX liquidity thesis over the next 1-3 months.
